Do I need to regear?

Hey All,

I am new to the Jeep world and am wondering if I need to regear after my recent purchase/mod:

2013 Jeep Wrangler Unlimited Sport (Manual)
BDS 2" suspension lift kit w/Fox shocks & steering stabilizer
KMC XD Strike 17" wheels
Goodyear MTR LT255/75R17 (32.01" x 10") tires

Acceleration seems a little sluggish. Have to downshift a lot more.

Did I do something wrong here?

Nothing you did "wrong", just the tire size and weight. Regear is up to you really. Depends if you think you'll go to a bigger tire and if you can afford to regear twice. Id imagine if you had factory 3.73s or 4.10s you'll b ok till you go bigger especially on a clutch

Thanks for the info.

I forgot to mention current rear axle ratio is 3.21s.

Yeah, with 3.21 you will notice a difference but I wouldn't regear until you were sure on your final tire size so your only buying one gear set

I am surprised that you feel sluggish with 32's. Tons of guys swap in Rubicon take off BFG KM's which are 32". Even on the old 3.8L with 3.21's isn't bad.

You didn't do anything wrong, 97 is right. If you are going bigger in the future look into a re-gear of 4.56.

My 2012 sport came from the factory with 255/75R17 tires with the 6 speed and 3.21 gears. It's not a sports car but it will get around fine. I tend to hold it in a lower gear longer and it accelerates acceptably.

I bought this combo with the intention of swapping gears when I go to 35's. But for daily driving around town it's fine for now.

255's are a stock tire size. Like others have said wait to regear until you are sure what you are going to end up with. You are looking at min. $1200 to regear.

Thanks for all the words of wisdom.

So if 255s are a stock tire size, did I even need to get the lift kit?

Purely from a functional perspective.

No. You didn't even need new wheels--those tires would fit on the stock 17" wheels.

The only thing the lift kit will do for you (other than looks) is that maybe--maybe--the lower backspacing on the wheels likely puts the tires in a worse position vis-a-vis your fender flares when you flex offroad. Ie, on stock wheels the flex would've sent the tire up into the interior of the fender flare, but now it will send it into the lower outside edge.

So I suppose the right answer is likely that you didn't need new wheels or a lift, but once you got the wheels the lift was probably a good idea.

I got the 16" wheels with my package. Never liked the looks of them.

I kept everything as basic as possible to get the lowest price from the dealership. Had to get the Connectivity Package unless I wanted to wait for a custom order.

Ended up paying 26500 OTD.

Oh, and got the hardtop with it too.
